Mathcad

Good morning, I would like to know if anyone knows why this event happens, it turned out that I was working in mathcad 6.0 and my computer turned off, once I started it again I tried to open mathcad to continue with my programming and the program never opened again, it only opens that green window and then closes.   Translated with DeepL TranslatorTranslated by Hedy Jin, Nov 26th, 2021 ---------------------------------------------------------------------------------------------- buenos dias, quisiera saber si alguien conoce por que sucede este evento, resultó que estaba trabajando en mathcad 6.0 y mi ordenador se apago, una vez lo inicie de nuevo intente abrir mathcad para continuar con mi programación y el programa nunca volvió abrir, solo abre esa ventana verde y luego se cierra    

Hi, I converted a Mathcad 15 file to Prime and most of the results are different. These differences are due to the way in which Mathcad 15 and Prime append vectors vertically (see image). The solution I found was to transpose the matrix in Prime (see AzD_(j,jw) in image). Unfortunately for this particular Mathcad 15 file, there are several matrices that have the same issue and I would have to transpose each one of them individually. I wonder if there is a way to automatically change all the matrices in Prime that have this issue. I tried changing the range of (j,jw) without success. P.S. I attached a Prime and Mathcad file exemplifying the issue. Thank you!

Hello everyone I have been a bit puzzled by the error I get when using find with vector variables. I have defined a triangle DEF in 2 dimensions. I am searching for the coordinates of a 4th point S such that the sum of vectors from S to the other points is a zero vector (weighed with parameters g and t). Unfortunately, find does not find a solution.I thought maybe it was due to a divide by zero error, but adding the constraint that the product of the norms must be strictly positive does not solve the problem. The initial guess is already fairly close to the solution, so I don't believe it is the issue.I have attached the mcdx file as well as a screenshot for convenience. Any idea of what is going wrong ?  François

Hello, Right, mathcad and trig do not seem to be living a harmonious lifestyle. I ask why? I'm going through some fairly basic questions for an assignment for school and again on paper everything is rosy, but then mathcad is unconvinced. I am seeming unable to input the inverse trig functions in any form which I know (sin^-1, asin) and then as you can see in question 8 in the file attached the answer is absolutely wrong. What's the issue?! Is it me? Admittedly quite possible but I think I have tried all of the obvious approaches but I am likely wrong. thank you in advance for any help which you can offer me! Much MathCad love,Rowan 

Hello all, several days ago, I've updated my MathCad version to Prime 7.0.0.0.However, now I'm facing problems with my old scripts as it seems that the new version is not able to simplify as good as the old version. For example:   Obviously, the equation is 0 if test is a real number.Also, the equation was simplified to 0 in the old version. Even if I set test = 1, it is not simplified: Is there any possibility to improve this new behavior?Or is a different semantic required in the new version? Thanks in advance and best regards!

Apparently, https://www.poshenloh.com/quadraticdetail/ shows a 'new" way of solving quadratic equations.It is described as "computationally-efficient, .."  Math Genius Has Devised a Wildly Simple New Way to Solve Quadratic Equations (sciencealert.com)Does anyone know how to do timing tests in mathcad to check the difference in speeds in the "new" and the generally old method?  

Dear mathcad'ers,   I really need help.   I am trying to make an iteration process for an airlift reactor. The iteration procedure can be found in the word document, together with the mathcad file, below. However, I Mathcad isn't able to find the previous value of an parameter. How can I solve this?   Thanks for your expertise and help.   Tim

Hey, I would like to do the following in Mathcad Prime 7.0:So an index in an index. At the moment, whenever i press the index button in an index it sets me back up to normal but doesn't do another index.Is there a way to do it?Greetings

Is there a way to use plot phasors of voltages and currents (complex numbers in rectangular or polar form)? I would like to do this without creating custom functions, if possible.

I've imported a MathCAD 15 document into PTC Mathcad Prime 7.   I want to add grids to the plots.  I don't know how.  The documentation doesn't match what I see in PTC Mathcad Prime 7.   Not sure what to do.

I was given the link to download the trial version of the software by a member of the sales department. I went through the entire installation process and even received a license file via email. But when I open the Prime 7.0 software, in the File-Options it says no valid license found and all the functionalities are locked down. I am unsure how to solve this issue. This is what is seen in the license options:Lizenzstatus: UngültigLizenztyp: Keine LizenzAusstellungsdatum:Ablaufdatum:Host-ID: 2C-FD-A1-B6-CE-68Datei: C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.dat23.11.2021 16:03:06 : Die Lizenzanfrage ist fehlgeschlagen.Requesting MathcadPrime ...C:\ProgramData\PTC\Mathcad Prime\license\MathcadLicense.dat: (-103) Cannot checkout an uncounted license within a Windows Terminal Services guest session.

Hi all trying to get a mathcad function that returns an rounded match from a table the example is attached, I could put the figures within a graph and use the interpret function but i want a rounded answer to the next D610. i.e. for the attached sheet the solution would be 1.7m when the looking for an F of 27kNm in column F610  i.e. not an exact match, therefore selecting the higher value in column D610. i.e. in excel this would be a Vloop/match function.   ThanksBen

https://www.engineering.com/story/my-top-3-engineering-nightmares-expert-shares-the-truth-on-software-selection Anji Seberino, the head of our PTC Mathcad Application Engineer team, recently took some time to interview with engineering.com about her top 3 engineering nightmares accumulated from her own experience as an engineer. From missing units to debugging custom code to trying to reverse engineer IP stored in crazy, inherited spreadsheets, you too have probably faced these issues in your time in the industry when not everyone is using the right software and processes. Let us know what you think of the interview!

I am getting very strange error in Mathcad Prime Has anyone seen it. If yes how to solve this and where I am doing wrong 

Is there  a simple way to display a complex number in polar form (that includes the angle operator) without manually finding the magnitude and angle? 

Whilst playing around with the Is Element Of operator in Mathcad Express 7, I noticed the following:     I was surprised to see that Mathcad thinks that NaN is a Real (and hence Complex), but not an integer.      Is this just a case where one should expect inconsistent results from applying non-NaN-specific functions to a NaN?  If so, I think there should be a warning about this behaviour on the Is Element Of Help page.   Or is it something that should be corrected?   The red error arises because only the symbolic processor can test for rationals and Mathcad Express doesn't have symbolics.  Consequently, I don't know whether Is Element Of's NaN behaviour extends to symbolics.   Stuart   I discovered the above whilst trying to write a couple of data type identification functions.      

HiI am currently converting files from 15 to Prime which must of it have been successful.I have an issue with this equation below:Here are the input:I can plot the data easily, but I cannot get the intersection point which im trying to with the root function.It works in mathcad 15:    

I have created a vector that has both positive and negative values. I would like to sum all the positive values, return the number, and then separately sum the negative numbers and return the number. Is this possible? Thanks,  Ross 

I want to purchase MathCad Prime 7

I am using Mathcad Prime 7.0 7.0.0.0.Our first installation of MathCad Prime is installed on a Windows10 client. We want to open our xmcd files (from MathCad15 M050) and see how the layout/formula's looks like in Prime.Because we can't open MathCad files (xmcd) directly in Prime, we have to convert these xmcd files first before using in Prime.When using the Conversion option in Prime, we get the following error:Exception data:System.Runtime.InteropServices.COMException (0x80040CB6): Unknown Errorat mcautomation.IMathcadWorksheets.Open(String pFileName)at ConverterLoader.XmcdToMcdxConverter.StartConverting(String originalFileName, String destinationFileName)at ConverterLoader.XmcdToMcdxConverter.TryConvertWorksheet(String originalFileName, String destinationFileName)at ConverterLoader.XmcdToMcdxConverter.ConvertWorksheet(String originalFileName, String destinationFileName, String mathcadVersion)We've tried several files, but none of them we've managed to convert to Prime.We could use so

I got a new computer and need to move my Mathcad program and license to that computer.

Hello Experts, I am pretty new to mathcad and unable to understand what I am missing in program I have written.  Any help is appreciated
